Abstract

The utility model discloses a kind of dust absorption blackboard eraser, comprise the upper cartridge body and lower box body that are interconnected, described upper cartridge body and lower box body adopt hinge to be flexibly connected, upper cartridge body top is provided with opening, Wiper plate is slidably connected in opening, be reserved with suction layered suture between described Wiper plate and opening sidewalls, be provided with the screen pack separating upper cartridge body and lower box body inner space at lower box body top, the exhaust outlet place below screen pack is provided with blower fan.The utility model is reserved with suction layered suture on the upper cartridge body of blackboard eraser, when left and right blackboard wiping, suction layered suture is always in the side that dust drops, and the dust dropped is due to the suck-back effect of blower fan, all be adsorbed on screen pack by inhaling layered suture, thus realize dustless operation.When screen pack dust is too much time, upper cartridge body and lower box body can be opened, the dust on attachment screen pack be shaken off down, conveniently uses next time.

Description

A kind of dust absorption blackboard eraser
Technical field
The utility model relates to a kind of blackboard eraser, particularly relates to a kind of dust absorption blackboard eraser.
Background technology
At present, conventional blackboard eraser has brush type and felt type two kinds of forms substantially, all uses sliding friction principle removing blackboard chalk writing.The material such as hairbrush, felt has good suction-operated to dust, when brush type or felt type blackboard eraser surface ratio cleaner time, it has good wiping effect, also not easily dust is produced, but the suction-operated of any material is all limited, felt is no exception, therefore, after brush type or felt type blackboard eraser employ a period of time, the chalk dust that its adsorption one deck is thick, now, if continue to carry out blackboard wiping with it, not only can not blackboard-cleaning is clean, and can make that chalk dust flies upward, contaminated air, infringement health equally everywhere.
Summary of the invention
The purpose of this utility model is, provides the dust absorption blackboard eraser that a kind of structure is simple, easy to use, can reach " dustless " wiping effect, to overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of dust absorption blackboard eraser, comprise the upper cartridge body and lower box body that are interconnected, described upper cartridge body and lower box body adopt hinge to be flexibly connected, upper cartridge body top is provided with opening, Wiper plate is slidably connected in opening, be reserved with suction layered suture between described Wiper plate and opening sidewalls, be provided with the screen pack separating upper cartridge body and lower box body inner space at lower box body top, the exhaust outlet place below screen pack is provided with blower fan.
Described Wiper plate two ends are slidably connected guide rod, and guide rod is arranged on the opening two ends on upper cartridge body.
Described blower fan is connected with the battery case be arranged in lower box body, and by being arranged on the switch control rule on lower box body outer wall.
Described screen pack is flexible fiber screen pack, has good suction-operated, and easy cleaning.
Owing to adopting technique scheme, the utility model has the advantage of: the utility model is reserved with suction layered suture on the upper cartridge body of blackboard eraser, when left and right blackboard wiping, suction layered suture is always in the side that dust drops, and the dust dropped is due to the suck-back effect of blower fan, all be adsorbed on screen pack by inhaling layered suture, thus realize dustless operation.When screen pack dust is too much time, upper cartridge body and lower box body can be opened, the dust on attachment screen pack be shaken off down, conveniently uses next time.Therefore, the utility model not only structure is simple, easy to use, realizes the effect reaching " dustless " wiping, avoids chalk dust to fly upward everywhere, contaminated air, infringement health.

Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
The structural representation of dust absorption blackboard eraser as shown in Figure 1, comprise the upper cartridge body 3 and lower box body 5 that are interconnected, described upper cartridge body 3 and lower box body 5 adopt hinge 4 to be flexibly connected, upper cartridge body 3 top is provided with opening 10, Wiper plate 1 is slidably connected in opening 10, be reserved with between described Wiper plate 1 and opening 10 sidewall and inhale layered suture 12, the screen pack 11 separating upper cartridge body 3 and lower box body 5 inner space is provided with at lower box body 5 top, described screen pack 11 is flexible fiber screen pack, and exhaust outlet 9 place below screen pack 11 is provided with blower fan 8.Described Wiper plate 1 two ends are slidably connected guide rod 2, and guide rod 2 is arranged on opening 10 two ends on upper cartridge body 3.Described blower fan 8 is connected with the battery case 7 be arranged in lower box body 5, and is controlled by the switch 6 be arranged on lower box body 5 outer wall.Therefore, when left and right blackboard wiping, suction layered suture 12 is always in the side that dust drops, and the dust dropped is due to the suck-back effect of blower fan 8, is all adsorbed on screen pack 11 by inhaling layered suture 12, thus realizes dustless operation.When screen pack 11 dust is too much time, upper cartridge body 3 and lower box body 5 can be opened, the dust on attachment screen pack 11 be shaken off down, conveniently uses next time.
